Description
Technical field
The present invention relates to Large Precast Members hoisting technology field, particularly belong to a kind of use suspension rod of falling T-shaped and carry out large-scale
The devices and methods therefor of prefabricated component lifting.
Background technology
At present, along with the development of water transport engineering project technology, concrete lifting component technology is increasingly mature, but at harbour, code
It is all to use suspension ring and " suspension rod of falling T-shaped " to carry out concrete lifting component as suspender that head builds the central overwhelming majority, is using "
T-shaped suspension rod " lifting time, because its hole for hoist is reserved relatively deep, easily cause land peace suspender, to pluck suspender difficulty, work efficiency under water low etc.
Phenomenon.
Summary of the invention
It is an object of the invention to provide a kind of novel Large Precast Members hanging apparatus and method, to reach operation letter
List is quick, reduce cost, increase substantially the purpose of work efficiency.
Large Precast Members hanging apparatus provided by the present invention, has the bar of falling T-shaped and auxiliary device, it is characterised in that
Described auxiliary device includes fixed block and locked instrument, and locked instrument is the pin-and-hole being welded on the bar of falling T-shaped and joins therewith
Closing the pin used, fixed block is provided with jack, and fixed block is positioned on the upside of the T prefix of the bar of falling T-shaped, and the bar of falling T-shaped is provided above
Rotary handle.
Large Precast Members hanging method provided by the present invention, it is characterised in that comprise the steps:
1) the land installation of suspender
Step 1-1, the suspension rod of falling T-shaped and auxiliary device are winched to above component by operator simultaneously, and workmen is same by it
Step moves to component and reserves directly over hole for hoist；
Step 1-2, makes fixed block and T prefix on same level axis, and the big hook of crane ship is slowly drop down on component
Fang Jinhang coarse positioning；
Step 1-3, crane ship continues to weigh in the hand hook, and workmen is keeping fixed block and the T prefix shape at same level axis
Under state, fixed block and T-shaped bar are put into component and reserves hole for hoist, and pinned in pin is inserted the jack of fixed block；
Step 1-4, after fixed block arrives position of rotation, stops declining, will pull out on pin, and T-shaped bar is rotated 90 by workman
Degree, makes T prefix vertical with the axis of fixed block, and pin is stayed in pin-and-hole, and workman withdraws scene, and crane ship starts lifting；
2) component is installed under water and suspender is extractd
Step 2-1, Large Precast Members is hoisted under water by crane ship, and Divers will be pre-under the guidance of technical staff
Component processed is arranged on design attitude；
Step 2-2, after component installation, crane ship is weighed hook in the hand and is relaxed one's efforts to steel wire rope, and Divers puts in place；
Step 2-3, Divers the bar of falling T-shaped is rotated to fixed block same level axis, insert pin, and withdraw
To safety zone；
Step 2-4, because fixed block can keep the suspension rod of falling T-shaped vertical center in hole for hoist reserved by component, crane ship can
Successfully suspender is left the water；
Step 2-5, enters the lifting flow process of next component.
Present invention effectively prevents existing Large Precast Members hoisting process to install, extract the hole clipping etc. that T-shaped bar easily occurs
The generation of phenomenon, is effectively shortened the bottom time of Divers, reduces the probability of happening of bends, has ensured its people
Body safety；This method has good effect easy and simple to handle, safe and reliable, that work efficiency is high.
Accompanying drawing explanation
Accompanying drawing part discloses the specific embodiment of the present invention, wherein
Fig. 1, fixed block top view of the present invention；
Fig. 2, the structural representation of hanging apparatus of the present invention；
Fig. 3, hanging apparatus of the present invention enters concrete test block view；
Fig. 4, view after T-shaped bar 90-degree rotation of the present invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, Large Precast Members hanging apparatus provided by the present invention, there is the bar of falling T-shaped 5 and auxiliary
Device, wherein, described auxiliary device includes fixed block 2 and locked instrument, and locked instrument is the pin being welded on the bar of falling T-shaped
The pin 4 of hole 3 and matched use, fixed block is provided with jack 6, and fixed block is positioned on the upside of the T prefix 1 of the bar of falling T-shaped,
The bar of falling T-shaped is provided above rotary handle 7.
Large Precast Members hanging method provided by the present invention, is first the land installation of suspender, and operator will fall
T-shaped suspension rod and auxiliary device winch to above component simultaneously, and workmen is synchronized to move to component and reserves directly over hole for hoist；
Making fixed block and T prefix on same level axis, the big hook of crane ship is slowly drop down to above component carry out coarse positioning.
As it is shown on figure 3, after hanging apparatus carries out coarse positioning above component 8, crane ship continues to weigh in the hand hook, workmen exists
Keep fixed block and T prefix when same level axis, fixed block and T-shaped bar are put into component and reserves hole for hoist 9
In, and is pinned in pin is inserted the jack of fixed block, fixed block and the close contact of reserved hole for hoist during this, simultaneously
Serve the effect of location, it is to avoid the hole clipping phenomenon that T-shaped bar displacement causes.
As shown in Figure 4, after fixed block arrives position of rotation, stopping declining, will pull out on pin, T-shaped bar is rotated 90 by workman
Degree, makes T prefix vertical with the axis of fixed block, and pin is stayed in pin-and-hole, and workman withdraws scene, and crane ship starts lifting.
After Large Precast Members is hoisted under water by crane ship, Divers under the guidance of technical staff by prefabricated components
It is arranged on design attitude；After component installation, crane ship is weighed hook in the hand and is relaxed one's efforts to steel wire rope, and now Divers is by the bar of falling T-shaped
Rotate to parallel with fixed block, insert pin, and withdraw to safety zone；Because fixed block can keep the suspension rod of falling T-shaped in lifting
Vertical center in hole, suspender can successfully be left the water by crane ship.
The hanging apparatus of the present invention, coordinates the reserved hole for hoist in Large Precast Members to use, and the most efficiently, safety can
Lean on.
